Description

Technical Field

[0001] This invention relates to the field of camera devices, and more specifically, to a stabilization structure, a camera device, and an electronic device. Background Technology

[0002] Miniature autofocus cameras are widely used in mobile phones, automobiles, drones, security monitoring, smart home products, and other applications. A typical miniature autofocus camera uses a voice coil motor to drive the lens along its optical axis. A typical voice coil motor mainly consists of a housing, a lens holder that moves within the housing via upper and lower springs, a drive coil mounted on the lens holder, and at least two drive magnets fixed within the housing. The lens is fixed to the lens holder, and the housing has a light-transmitting hole facing the lens. During operation, a control chip controls the current input to the drive coil, causing the magnets to interact with the drive coil and drive the lens holder to move against the spring force, thus achieving autofocus. However, during photography and video recording, the lens may not remain perfectly stable due to human shake or other reasons, resulting in some displacement. This affects the camera's focus and the amount of light entering, consequently impacting the quality of the image acquired.

[0003] To address this, existing technologies have developed image stabilization actuators that drive a voice coil motor to move in a direction perpendicular to the lens's optical axis, thereby compensating for lens shift caused by human shake or other factors. Existing SMA (Sound-Magnetic-Mount) image stabilization actuators utilize the thermal expansion and contraction properties of shape memory alloy wires to drive the voice coil motor in a direction perpendicular to the lens's optical axis. However, existing SMA actuators suffer from complex structures and difficult assembly processes. Furthermore, existing technologies with focusing and image stabilization functions also suffer from insufficient thrust from the drive motor, complex circuit connections, and numerous components, leading to significant assembly difficulties.

[0004] Therefore, existing technologies suffer from poor performance of the image stabilization structure in camera devices. Summary of the Invention

[0015] Furthermore, the circuit connector also includes a thermistor and at least two second energized pins, the thermistor being disposed on the second energized pins and electrically connected to the second energized pins.

[0016] Furthermore, the two SMA wires located on two adjacent sides of the base plate assembly are electrically connected to the same upper jaw or the same lower jaw, respectively.

[0017] Furthermore, the base plate assembly also includes multiple support blocks, which are disposed on the side of the circuit connector facing the reed body, with each reed body corresponding to at least one support block.

[0019] Furthermore, the connecting end of the first energized pin and the connecting end of the second energized pin extend out of the accommodating space.

[0020] Furthermore, the image stabilization structure also includes a substrate, which is disposed between the reed assembly and the lens drive assembly, and the substrate assembly is electrically connected to the reed assembly and the lens drive assembly respectively.

[0021] Furthermore, the substrate is provided with multiple clearance notches for avoiding the upper claws of the reed assembly.

[0022] Furthermore, the substrate is made of a metal material; and / or the substrate includes a plate body and an embedded member, the plate body being made of a plastic material and the embedded member being made of a metal material, the plate body being connected to the reed assembly and the lens drive assembly respectively, at least a portion of the embedded member being embedded inside the plate body, and the embedded member being electrically connected to the reed assembly and the lens drive assembly respectively.

[0023] Furthermore, the outer casing includes: a shielding cover, which covers the base and forms an accommodating space with the base; and a housing, which is fitted over the shielding cover and connected to the base.

[0025] According to another aspect of the present invention, an electronic device is provided, including the above-described camera device.

[0026] Applying the technical solution of this invention, the anti-shake structure in this application includes a housing and a base. The housing covers the base and forms an accommodating space with the base.

[0027] When using the image stabilization structure of this application, since the reed assembly is electrically connected to the base plate assembly and both ends of the SMA wire are electrically connected to the reed assembly and the base plate assembly respectively, when the SMA wire is energized and retracts, the SMA wire can drive a portion of the reed assembly to move relative to the base plate assembly, thereby driving the lens drive assembly to move in the XY plane. Furthermore, since there are multiple SMA wires, the lens drive assembly can rotate in the XY plane or move along the X-axis and / or Y-axis.

[0041] To address the problem of poor performance of image stabilization structures in existing camera devices, this application provides an image stabilization structure, a camera device, and an electronic device.

[0042] Furthermore, the electronic device in this application has a camera device, and the camera device has the following image stabilization structure, thereby ensuring that the camera device in this application has the function of horizontal image stabilization.

[0043] Meanwhile, the electronic device in this application may be a mobile phone, tablet computer, laptop computer, etc., with photo taking, video recording or scanning functions.

[0044] like Figures 1 to 7 As shown, the image stabilization structure of this application includes a housing 10 and a base 20. The housing 10 covers the base 20 and forms an accommodating space with the base 20. The image stabilization structure also includes a base plate assembly 30, a spring assembly 40, SMA wires 50, and a lens drive assembly 60 disposed inside the accommodating space. The base plate assembly 30 is disposed on the base 20; the spring assembly 40 is disposed on the side of the base plate assembly 30 away from the base 20, and the spring assembly 40 is electrically connected to the base plate assembly 30, and at least a portion of the spring assembly 40 is movable relative to the base plate assembly 30; there are multiple SMA wires 50, one end of which is connected to the base plate assembly 30, and the other end of which is connected to the spring assembly 40; the lens drive assembly 60 is disposed on the side of the spring assembly 40 away from the base plate assembly 30, and at least a portion of the spring assembly 40 is movable relative to the base plate assembly 30; there are multiple SMA wires 50, one end of which is connected to the base plate assembly 30, and the other end of which is connected to the spring assembly 40; the lens drive assembly 60 is disposed on the side of the spring assembly 40 away from the base plate assembly 30, and at least a portion of the spring assembly 40 is movable relative to the base plate assembly 30. A small portion is electrically connected to the SMA wire 50, and at least another portion of the reed assembly 40 is electrically connected to the lens drive assembly 60. At least a portion of the lens drive assembly 60 is fixed to the reed assembly 40, and at least another portion of the lens drive assembly 60 can move relative to the reed assembly 40 in a direction close to or away from the base 20. When the SMA wire 50 is energized, the multiple SMA wires 50 drive the reed assembly 40 to move relative to the base plate assembly 30, and the reed assembly 40 drives the lens drive assembly 60 to move in the XY plane.

[0045] When using the image stabilization structure of this application, since the reed assembly 40 is electrically connected to the base plate assembly 30 and both ends of the SMA wire 50 are electrically connected to the reed assembly 40 and the base plate assembly 30 respectively, when the SMA wire 50 is energized and retracts, the SMA wire 50 can drive a portion of the reed assembly 40 to move relative to the base plate assembly 30, thereby driving the lens drive assembly 60 to move in the XY plane. Furthermore, since there are multiple SMA wires 50, the lens drive assembly 60 can rotate in the XY plane or move along the X-axis and / or Y-axis. Simultaneously, since the lens drive assembly 60 of this application can be electrically connected through the reed assembly 40, the internal structure is simplified compared to conventional camera devices. Therefore, the image stabilization structure of this application effectively solves the problem of poor performance of image stabilization structures in existing camera devices.

[0046] Specifically, the reed assembly 40 includes multiple reed bodies 41, which are spaced apart on the base plate assembly 30. At least a portion of the reed bodies 41 are electrically connected to the SMA wire 50, and at least another portion is electrically connected to the lens drive assembly 60. Each reed body 41 is electrically connected to the base plate assembly 30, and at least a portion of the reed body 41 is movable relative to the base plate assembly 30. By setting multiple reed bodies 41, the movement of the lens drive assembly 60 can be controlled more flexibly, and the assembly of the anti-shake structure can be facilitated, reducing assembly difficulty. It should be noted that, in this application, setting multiple reed bodies 41 not only achieves high-precision and stable control, but also enables different circuit conduction functions through different reed bodies 41. Some reed bodies 41 achieve AF drive circuit conduction through electrical connection with lens support assembly, while others achieve OIS anti-shake drive circuit conduction through electrical connection with SMA wire 50, thereby replacing FPC power supply, reducing the number of parts, effectively simplifying the internal structure of the anti-shake structure, and also simplifying the assembly process and difficulty.

[0047] Specifically, the reed body 41 includes a body portion 411 and a connecting arm 412. The body portion 411 is movably disposed on the side of the base plate assembly 30 away from the base 20; one end of the connecting arm 412 is connected to the end of the body portion 411, and the other end of the connecting arm 412 extends around the edge of one side of the body portion 411 and is electrically connected to the base plate assembly 30. Furthermore, the reed assembly 40 also includes a plurality of upper claws 42. Each of the plurality of reed bodies 41 electrically connected to the SMA wire 50 is provided with at least one upper claw 42, and the SMA wire 50 is connected to the reed body 41 through the upper claws 42. The base plate assembly 30 includes a circuit connector 31 and lower claws 32. The reed body 41 is electrically connected to the circuit connector 31; there are multiple lower claws 32, and each lower claw 32 is electrically connected to the circuit connector 31 and the SMA wire 50 is electrically connected to the lower claws 32.

[0048] In one specific embodiment of this application, the circuit connector 31 includes a plurality of first energizing pins 311, and different first energizing pins 311 are electrically connected to different spring bodies 41 or different lower jaws 32. Preferably, the end of the connecting arm 412 is soldered to the first energizing pins 311. With this arrangement, one end of the connecting portion can be tilted toward one side of the circuit connector 31 and away from the lens support assembly, thereby increasing the gap between the connecting arm 412 and the lens support assembly, and thus effectively preventing contact between the connecting arm 412 and the lens support assembly during the movement of the lens support assembly together with the body portion 411.

[0049] Optionally, two SMA wires 50 located on two adjacent sides of the base plate assembly 30 are electrically connected to the same upper jaw 42 or the same lower jaw 32, respectively.

[0050] In one specific embodiment of this application, there are four reed bodies 41 and four SMA wires 50. The four reed bodies 41 are arranged in pairs opposite each other at the corners of the base plate assembly 30, and the four SMA wires 50 are arranged in pairs opposite each other on different sides of the base plate assembly 30. Two reed bodies 41 are electrically connected to two adjacent SMA wires 50, and the other two reed bodies 41 are electrically connected to the lens driving assembly 60. Furthermore, two adjacent reed bodies 41 are symmetrically arranged with the other two adjacent reed bodies 41. In this embodiment, there are two upper jaws 42 and two lower jaws 32. Two upper jaws 42 are arranged opposite each other on one diagonal line, and two lower jaws 32 are arranged opposite each other on the other diagonal line. The two ends of each SMA wire 50 are connected to adjacent upper jaws 42 and lower jaws 32, respectively. Since the lower jaw 32 is fixed to the circuit connector 31, and the upper jaw 42 is mounted on the reed body 41 and can move with the reed body 41, when energized, the SMA wire 50 retracts and drives the upper jaw 42 to move, thereby driving the reed body 41 to move, and thus realizing the movement of the lens drive assembly 60. Therefore, in this embodiment, by controlling the amount of electricity flowing through different SMA wires 50, different movement patterns of the lens drive assembly 60 can be achieved, thereby realizing the image stabilization adjustment of the lens on the lens drive assembly 60.

[0051] Furthermore, in the above embodiment, there are 8 first power-on pins 311, of which 6 first power-on pins 311 are used for electrical connection of SMA wire 50, and the other 2 first power-on pins 311 are used for electrical connection of drive coil of lens support assembly.

[0052] Of course, in this application, the number of SMA wires 50, reed body 41, upper claw 42 and lower claw 32 can be adjusted according to different actual situations and usage requirements.

[0053] Of course, the image stabilization structure in this application may also include a substrate 70, which is disposed between the reed assembly 40 and the lens drive assembly 60, and the substrate 70 is electrically connected to both the reed assembly 40 and the lens drive assembly 60. Since the lens support assembly in this application has the same structural composition as the lens support assembly in the prior art, including a lens support body, a driving magnet, a driving coil, an upper spring, and a lower spring, etc., placing the substrate 70 between the lens drive assembly 60 and the reed assembly 40 facilitates the electrical connection between the lens drive assembly 60 and the reed assembly 40. In other words, in actual use, the lens support assembly can be electrically connected before the entire substrate 70, and then the entire substrate 70 can be connected to different reed bodies 41, thereby effectively reducing the connection difficulty. Furthermore, the substrate 70 effectively ensures the stability of the lens support assembly.

[0054] Preferably, the upper claw 42 and the spring body 41 are integrally formed. Of course, in this application, the upper claw 42 and the spring body 41 can also be separate structures.

[0055] Optionally, the circuit connector 31 includes a thermistor and at least two second energized pins 312, with the thermistor disposed on and electrically connected to the second energized pins 312. This arrangement allows for the detection of the internal ambient temperature of the image stabilization structure, thereby ensuring the performance of the image stabilization structure.

[0056] Optionally, the base plate assembly 30 further includes a plurality of support blocks 33, which are disposed on the side of the circuit connector 31 facing the reed body 41, with each reed body 41 corresponding to at least one support block 33. Preferably, the base plate assembly 30 further includes a plurality of balls 34, and the support block 33 is provided with at least one mounting groove 331 on the side facing the reed body 41, with at least one ball 34 disposed in each mounting groove 331, and the side of the reed body 41 facing the base plate assembly 30 abutting against the ball 34. With this arrangement, when the reed body 41 moves under the action of the SMA wire 50, the friction force on the reed body 41 can be effectively reduced because the balls 34 support the reed body 41, thereby reducing the number of moving parts of the reed body 41. Furthermore, this arrangement can also reduce driving resistance, thereby improving the response speed of the anti-shake structure and reducing the driving power consumption of the driving device.

[0057] Optionally, the connecting end of the first power-on pin 311 and the connecting end of the second power-on pin 312 extend out of the receiving space. This arrangement facilitates electrical connection between the first power-on pin 311 and the second power-on pin 312 and other structures of the camera device.

[0058] Preferably, the substrate 70 is provided with a plurality of clearance notches 71 for avoiding the upper claws 42 of the spring assembly 40. With this arrangement, when the substrate 70 moves with the spring body 41, contact between the substrate 70 and the upper claws 42 can be effectively avoided, thereby reducing the movement resistance of the substrate 70. Furthermore, this arrangement can also effectively reduce the overall thickness of the anti-shake structure, thereby achieving a thinner and lighter design for the anti-shake structure.

[0059] Optionally, the substrate 70 is made of metal. This arrangement can further and effectively reduce the overall thickness of the image stabilization structure. It can also effectively improve the stability of the connection between the substrate 70 and the lens support assembly and the reed assembly 40. However, it should be noted that since the substrate 70 is made of metal, in order to avoid short circuits between different reed bodies 41 connected to the substrate 70, the substrate 70 needs to be configured into multiple parts.

[0060] Optionally, the substrate 70 includes a plate body and an embedded member. The plate body is made of plastic material, and the embedded member is made of metal material. The plate body is connected to the reed assembly 40 and the lens driving assembly 60, respectively. At least a portion of the embedded member is embedded inside the plate body, and the embedded member is electrically connected to the reed assembly 40 and the lens driving assembly 60, respectively.

[0061] Optionally, the housing 10 includes a shield 11 and a housing 12. The shield 11 covers the base 20 and forms an accommodating space with the base 20; the housing 12 is fitted over the shield 11 and connected to the base 20. This arrangement can effectively reduce magnetic interference to the lens support assembly.

[0062] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0063] 1. Effectively solves the problem of poor performance of the image stabilization structure in existing camera devices;

[0064] 2. Simple structure and stable performance.
